Capital Gains Tax (Rates)

The hon. Gentleman knows, as I do, that the two points that he makes are not as mutually contradictory as he suggests. There is a long history in this country of applying so-called "sin taxes" to alcohol and tobacco, and they have had the very desirable effect of helping to get people off smoking and of cutting their drinking. The success of those taxes is not perhaps as great as many hon. Members on both sides of the House would like, yet I am assured by the latest Red Book documents that the Treasury continues to raise a very substantial amount of money from both tobacco and drink excises. The reality is that, while green taxes will change behaviour, the responsiveness of behaviour is such that revenue will continue to be raised for a very substantial period. I have to say that, in the present circumstances, that point is likely to commend itself to the Treasury, which always used to follow the motto of Colbert, the finance minister of Louis XIV, who said that the art of taxation lay in plucking the maximum number of feathers from the goose with the minimum amount of hissing. In that context, green taxes certainly are a very justifiable way to pluck the maximum number of feathers. I shall give way once more, to the hon. Member for Edinburgh North and Leith (Mark Lazarowicz), and then I shall wind up and let the debate make progress.
